Abstract: VALVE     This application is a division of my copending Canadian application Serial No. 369,588, filed April 1, 1981.   Abstract of the Disclosure A valve and particularly a safety valve for use in controlling flow from a well in which an external motor is utilized to shift the actuator of a valve such as a ball valve.  The reciprocating rod of the motor is protected by resilient means between the crosshead attached to the motor and the reciprocating actuator.  The actuator is latched when the valve is in the open position so that it cannot be moved to closed position except by movement of the reciprocating motor.  The valve and seat assembly are designed to be re-placed as a unit and can be fabricated as a subassembly with the valve in exact open alignment when the reciprocating actuator is in full valve open position as determined by a stop against which the valve member bottoms.    The valve may have its actuator moved beyond the normal reciprocating range for opening and closing of the valve member to permanently lock the valve member in full open position without hindering further reciprocation of the actuator so that it can be used as a control for a secondary valve.  The housing and actuator are provided with latch means and a secondary valve with a secondary actuator are landed in the housing and in the actuator so that reciprocation of the actuator then moves the secondary valve between open and closed positions.

The brake shaft (18) is coupled to the propeller shaft to rotate there-with.  Also included is a brake  (64,74) and a lock device (38).  The brake  (64,74) is mounted in the hous-ing (10) and has a spaced plurality of frictional plates (64) for frictionally resisting rotation of the brake shaft (18).  This  brake (64,74) is reciprocatable between an operative and an inoperative position.  The lock device (38) is mounted in the housing (10) and can reciprocate between an unlocked and locked position.  This lock device (38) can, in its locked position, inhibit ro-tation of the brake shaft (18).  The forgoing equipment can stop a propeller shaft by first frictionally coupling the  brake (64,74) to the propeller shaft, allowing the coupled portion of the  brake (64,74) to rotate therewith. The brake (64,74) may then be actuated to transmit a resisting torque to stop the propeller shaft.  There-after, the propeller shaft may be positively and mechani-cally locked with a locking device (38) to prevent further rotation.

Abstract: ABSTRACT A carrier carton of the "suitcase" type in which a divider-handle assembly, made from a single blank of sheet material, is mounted in a shell, also made from a single blank.  In the divider-handle assembly, respective juxtaposed divider panels are hingedly connected, at one end, to shoulders of respective plies in the handle assembly, which have weakened parts for rupture to allow separation of the handle part from the divider part for up and down movement.  The divider-handle assembly is fashioned from a single blank in which the divider part includes elongated hingedly connected divider panels hingedly connected endwise to handle sections of a handle part made up of six handle sections hinged together for folding into juxtaposition and gluing together.  The shell is formed from a single blank in which integral first and second parts are arranged in L-shape so that they can be juxtaposed and glued together with the divider-handle assembly between them to provide a carton in folded condi-tion, ready to be squared up.  A method of forming the divider-handle assembly from the blank in which the handle sections are progressively juxtaposed, together with a reinforcing flap, and glued together to form an assembly which is interposed between the divider panels and which are finally juxtaposed, with the handle assembly between them, for sliding between stowed and operative position.

Abstract: OBJECTIVE REFRACTOR FOR THE EYE               Abstract of the Disclosure An objective refractor for the eye is disclosed in which knife-edge optics are utilized.  The knife-edge optics cause characteristic illumination of the retina so that components of sphere and astigmatism can be identified. Provision for remote reading of the characteristic images is provided with the result that two orthogonally disposed knife-edge images can identify the sphere, cylinder and axis required for prescriptive patterns giving the direction and magnitude of required prescriptive change.  A system of at least two orthogonally disposed, (and preferably four), knife edges with weighted lighting is disclosed for detection Utilization of the knife-edge images is made possible by the detection of the low light level images at a detector having low noise level.  A photo-sensitive element divided into a plurality of photo-discrete segments has light from the images proportionally dispersed over its surface.  Such dispersion occurs through a matrix of wedge-shaped segments or alternately in the form of optical elements having cylindrical components.  This dispersion of the light when used in combination with push-pull knife-edge patterns herein disclosed produces detectable low level refractive signal. An embodiment using an optic having a plurality of side by side optic elements, each element having the effect of crossed cylinders, is disclosed with the detector.  Separate independent and non-interactive positional information on one hand, and refractive information on the other hand, is provided.  Consequently the disclosed refractor is insensi-tive to adjustment and can accommodate a large range of pupil configuration with insensitivity to local retinal variations in light emission.

Abstract: Abstract of the Disclosure An orthogonal code division multiple access communi-cations system is disclosed involving multiple users while pro-viding orthogonal operation, meaning that there is substantially zero interference between users.  All of the users employ a mutually different time permutation of the same multi-bit direct sequence pseudo noise code with a synchronous time reference for all of the users being established through a central node or station which communicates with all of the users preferably through a loopback synchronous timing scheme.  Each pseudo noise code is followed by an extra processing bit that balances the number of one and zero bits in the composite information bit which has the effect of providing a code structure which will have a cross-correlation value of zero with the other time permutated codes which enables the system to operate as an orthogonal system.
